Development of Biodegradable Lubricants - The Rise of a New Material to Support Sustainable Industry (1999, Japan)

In the late 1990s, Japan was becoming increasingly concerned about the environmental impact of industrial activities, particularly water and soil pollution. Lubricants were widely used in machinery and equipment and automobiles, but petroleum-based lubricants were not easily decomposed in nature when disposed of or leaked, and their adverse impact on the ecosystem was pointed out. Under these circumstances, the development of biodegradable lubricants emerged. This new material, based on vegetable oil, was revolutionary in that it decomposes naturally in a short period of time after use, greatly reducing the burden on the environment.

Particular attention was paid to its use in waterside and agricultural machinery. When used in environments close to nature, such as river construction, forestry, and agricultural tractors, the effect of the practical application was clearly demonstrated by minimizing the impact at the time of leakage. The background to this is the tightening of environmental regulations that was underway in Europe. Germany and Scandinavian countries had already introduced biodegradable lubricants in accordance with the regulations, and Japan followed this trend by hurrying product development and standardization.

This movement was also closely related to the acquisition of ISO 14001 certification, which was spreading in Japan at the time. Companies were introducing environmentally conscious products as part of their environmental management systems, which led to an improved corporate image and reputation among business partners. It was also linked to the green procurement system promoted by the Environment Agency and environmental labeling systems such as the Eco Mark, and biodegradable lubricants became a concrete option to realize the sustainability strategy of the industry.

Related technologies included research on additives to improve the oxidation stability of vegetable oils and the development of synthetic ester-based lubricants. This improved durability and viscosity characteristics, ensuring performance comparable to conventional petroleum-based lubricants. These technological advances laid the foundation for both environmental performance and economic rationality, and encouraged a shift in industrial structure toward a recycling-oriented society.
